This happens on a Win 8.1 PC, as a result of "ember serve", with no modifications done after an error free, ember new MyApp.

From my research:

"Error: EPERM: operation not permitted, symlink" means that there is a permissions issue.
So I made sure my Windows 8.1 local security policy is set to admin and I'm running my cmd window with admin privileges. I've also reinstalled and updated Ember-CLI and NPM, globally. I'm not sure what else to try.

Also, the build is very slow, over 5 minutes on a normally fast PC. I have ember-cli-windows installed and it's still very slow.

Editorial comment: This seems like a pretty big fail for a "system" fresh out of the box. If it's this buggy without even adding new code... maybe I should invest time with Angular 2.0?

  • have you had any success? Commented Mar 31, 2016 at 0:21
  • no luck. I reinstalled all of it, per the Ember website instructions, and I get the same error. I have no idea how to trouble-shoot this. Commented Apr 2, 2016 at 0:16

    Update-not much to go on, but the error has something to do with it being on a mapped drive. I set up a project on a local partition on the same machine (which is a virtual machine) and it worked. Commented Apr 10, 2016 at 22:21
  • I believe I have later found out that atom is having issues on windows by locking folders which have been opened in the projects sidebar. I have since stopped using this plugin so can't confirm meddling with this changes things Commented Apr 11, 2016 at 10:07
  • I'm having the same issue except it is happening inside of my docker container Commented Apr 14, 2016 at 20:54

Thanks but I already tried that. "...local security policy is set to admin and I'm running my cmd window with admin privileges. "
